YUP fares used to book into an F fare class right?
A few months ago, in order to get their fare charts ready for real Premium Economy, AA changed the fare classes on all domestic flights. The "First" cabin now books into Business
class fare buckets, while still calling the cabin "First". Only the 3 class transcons (JFK-LAX/SFO, selected MIA-LAX) have F coded seats.
Add in the changes QF have done to the earn rates, it is unlikely you'll net those sorts of SC:$ rates.
